Shims definitely do not work with the Fiesta’s ABS sensors.. Don’t bother trying. It was fine until I went to the track and pushed the car hard enough to activate it. As soon as that happened it limped. Fortunatley (or unfortunately) I ended up frying a sensor while I was out there. After that, the car was drivable, but TC or ABS were disabled by the ECU. Once I realized it wouldn’t limp, I went back out and hammered it on track again and absolutely loved it. I must’ve set off a yaw sensor or something on a fast lap because it limped again on a long carousel. This time the TC, ABS and EBrake lights were lit. After that episode, I pitted and rebooted the car which successfully cleared the EBrake light (TC and ABS were still solid). Mentally, I was spent so I called the shop and scheduled some time.
As far as oversteer goes, I had zero issues with the rear camber. The rear end followed through and I experienced very minimal understeer at turnout. I’m also on new 215/40-17 RT615K+ tires (hot temps 36/36) and custom BC/Swift coilovers that are corner balanced. I’m not sure how that compares to Jesse’s setup.
We ended up pulling the shims and installing washers to push the bottom of the hub out. Ghetto but works without nanny errors haha! We’ll see how it does on track next week.
